The greenness and sustainability of three different routes for the synthesis of (3R,3aS,6aR)-hexahydrofuro [2,3-b] furan-3-ol (bis-furan alcohol), an advanced intermediate for a group of HIV protease inhibitors, including the FDA approved darunavir, used in antiretroviral (ARV) therapy, were compared. The method involved a comparison of (i) waste generated using the E-factor and relative to industrial
三种合成(3 R,3a S,6a R)-六氢呋喃[2,3 - b ]呋喃-3-醇(双呋喃醇)的路线的绿色度和可持续性,一组高级中间体比较了用于抗逆转录病毒(ARV)治疗的HIV蛋白酶抑制剂,包括FDA批准的darunavir。该方法涉及以下方面的比较:(i)使用E因子产生的废物,以及使用创新的绿色吸入量(iGAL™)方法相对于工业基准的比较,(ii)根据溶剂强度(SI)和性能确定的溶剂用量GSK溶剂指南,以及(iii)Green Motion™根据MANE方法得出的分数。
A general preparation of β-substituted tryptophan esters
In order to obtain constrained analogues of tryptophane, five-membered lactams and lactones bearing 4-indolyl and 3-carboxylic groups were prepared in a completely diastereoselective manner, resulting in a trans relationship. Furthermore, the use of chiral precursors in the synthesis yielded enantiomericallypure compounds with three contiguous chiral centres.

A concise and efficient synthesis of (3R,3aS,6aR)-hexahydrofuro[2,3-b]furan-3-ol, a key buildingblock for several clinical and experimental HIV proteaseinhibitors including the highly important drug darunavir, was achieved via a one-pot procedure using furan and Cbz-protected glycol aldehyde as starting materials. A [2+2]-photocycloaddition between both reactants which can be prepared from wood-based
简明而高效的合成(3 R,3a S,6a R)-六氢呋喃[2,3- b ]呋喃-3-醇,它是几种临床和实验HIV蛋白酶抑制剂(包括非常重要的药物darunavir)的关键组成部分,通过一锅法使用呋喃和Cbz保护的乙二醇醛作为起始原料来实现。两种反应物之间的[2 + 2]-光环加成反应可以根据木糖化学原理从木质基原料制备,然后进行氢化和脂肪酶催化的动力学拆分,从而以高收率和高达99%ee的浓度提供了目标化合物。

6a,7-hexahydrooxazolo[3,2-c]oxazole and its 4-methyl analog were synthesized using (R)-phenylglycinol and (S)-alaninol as the chiral source, respectively. The ring opening reaction of the bicyclicoxazolidinones by an allyltrimethylsilane–titanium tetrachloride mixture afforded the corresponding substitution products with diastereoselectivity of up to ∼3:1. The major substitution product was readily
